AMD Radeon Pro WX 2100 vs NVIDIA TITAN V CEO Edition Comparison

The Verdict

The data presents a stark contrast between two professional-grade GPUs from different eras. The AMD Radeon Pro WX 2100 is a low-power, entry-level workstation card, while the NVIDIA TITAN V CEO Edition is a high-end compute monster. Based strictly on the benchmark figures, the TITAN V CEO Edition is in a completely different performance class, dominating in raw compute and graphics throughput. However, the data also reveals a surprising outcome: when looking at the average benchmark scores, the Radeon Pro WX 2100 (9,653) actually edges out the TITAN V CEO Edition (9,037) by a margin of approximately 6.8%. This is due to the specific tests used—the WX 2100 has scores in Geekbench OpenCL and Vulkan, while the TITAN V has scores in Passmark G2D and G3D. The TITAN V’s Passmark G3D score of 16,988 is massive, but the WX 2100’s Geekbench scores are also substantial. Therefore, the choice depends entirely on the workload: the WX 2100 is for basic professional tasks and legacy compatibility, while the TITAN V CEO Edition is for extreme compute and high-resolution rendering, despite its lower average in this specific dataset.

Architecture Differences

The architectural divide between these two cards is fundamental. The AMD Radeon Pro WX 2100 is built on the GCN 4.0 architecture, utilizing the Lexa chip, and is manufactured on a 14 nm process at GlobalFoundries. It contains 2,200 million transistors on a 103 mm² die, resulting in a transistor density of 21.4M / mm². In contrast, the NVIDIA TITAN V CEO Edition is based on the Volta architecture with the GV100 chip, produced on a 12 nm process at TSMC. This chip packs a staggering 21,100 million transistors onto an 815 mm² die, achieving a density of 25.9M / mm². This represents roughly a tenfold increase in transistor count and a significantly larger, denser chip.

The compute capabilities diverge sharply as well. The WX 2100 has 512 shading units, 32 texture mapping units (TMUs), and 16 raster output units (ROPs). It has no dedicated tensor or RT cores. The TITAN V CEO Edition, however, is equipped with 5,120 shading units, 320 TMUs, and 128 ROPs, and it includes 640 tensor cores. This massive difference in raw hardware resources explains the performance gulf. The memory subsystems are also completely different. The WX 2100 uses 2 GB of GDDR5 memory on a 64-bit bus, yielding a bandwidth of 48.00 GB/s. The TITAN V CEO Edition uses 32 GB of HBM2 memory on a 4096-bit bus, providing a colossal bandwidth of 868.4 GB/s. The TITAN V’s memory bandwidth is over 18 times higher. Furthermore, the TITAN V supports a higher DirectX feature level (12_1 vs 12_0) and a newer Vulkan version (1.4 vs 1.3).

Head-to-Head Benchmarks

The head-to-head benchmark data is absent, but the individual scores tell a clear story. The AMD Radeon Pro WX 2100 achieves a Geekbench OpenCL score of 8,536 and a Geekbench Vulkan score of 10,770. The NVIDIA TITAN V CEO Edition, on the other hand, posts a Passmark G2D score of 1,086 and a Passmark G3D score of 16,988. The G3D score is a massive victory for the TITAN V, representing a 96.9% advantage over the WX 2100’s Vulkan score, which is the closest comparable metric in the pack. However, the WX 2100's average benchmark score of 9,653 is higher than the TITAN V's average of 9,037. This is because the WX 2100's two Geekbench scores are relatively close to each other, while the TITAN V's G2D score is very low compared to its G3D score, pulling its average down. The TITAN V's G3D score indicates exceptional raw 3D rendering performance, while its G2D score suggests that 2D tasks are not its primary strength. The WX 2100 shows more balanced performance across the tests it was run on.

Where Each One Wins

The AMD Radeon Pro WX 2100 wins in scenarios that prioritize efficiency and balance. Its average benchmark score of 9,653 is higher than the TITAN V CEO Edition's 9,037, making it the better choice based on the aggregate data in this pack. With a TDP of only 35 W, it is an extremely power-efficient card that requires no power connectors and a modest 200 W PSU. Its compact 168 mm length and Single-slot design make it suitable for small form-factor workstations. The Geekbench OpenCL score of 8,536 and Vulkan score of 10,770 show solid performance for a professional entry-level card. It is a successor to the Radeon Pro GCN line and was released earlier, on 2017-06-03. This card is for users needing basic professional graphics acceleration without the power and space demands of a high-end card.

The NVIDIA TITAN V CEO Edition wins in every metric of raw compute power. Its Passmark G3D score of 16,988 is in a completely different league, indicating dominance in demanding 3D rendering and compute tasks. The 14.90 TFLOPS of FP32 performance and 29.80 TFLOPS of FP16 performance (2:1) are massive, and the 640 tensor cores provide dedicated hardware for AI and deep learning workloads. The 32 GB of HBM2 memory with 868.4 GB/s of bandwidth is essential for large datasets and high-resolution textures. It supports a newer DirectX feature level (12_1) and Vulkan version (1.4). However, this performance comes at a cost of 250 W TDP, requiring a 600 W PSU and dual-slot space. It is a predecessor to the GeForce 20 series and was released later, on 2018-06-20. The TITAN V CEO Edition is for professionals who need maximum compute performance and are not constrained by power, space, or the low average benchmark score in this dataset.
